    2. Use mechanism and reports pages to connect metrics to decisions.

    3. Practice debug and worked-example pages for review readiness.

    4. Close with checklist and silicon impact before deployment decisions.

    Senior review question

    Ask: what evidence connects this ML claim to a concrete VLSI workflow decision and owner signoff?

    Execution drill pack 1

    Use this pack to rehearse AI-for-VLSI decision making on ai-vlsi/neural-networks-basics: metric framing, mechanism proof, hardware implications, and release safety.

    Evidence checklist

    • Metric context includes workload, dataset slice, and revision tags.

    • Mechanism explanation links model behavior to observed outcome.

    • Hardware/runtime feasibility is profiled, not assumed.

    • Owner and rollback path are documented before rollout.

    Review prompts

    1. Which decision will this model output influence?

    2. What is the first failing layer when metric regresses?

    3. Which owner applies the smallest reversible fix?

    4. What validation matrix is required before deployment?
